The relationship between Konoha and the Uzumaki clan might be further strained. With Kushina leaving, Konoha would lose an important link to the Uzumaki. And other Uzumaki members might see this as a sign that Konoha is not a safe place for them.
The story's power dynamics would shift. Naruto, with Kushina's training, could become a much more powerful ninja at a faster rate. This could change the balance of power among the villages. Also, the Akatsuki might target them differently if they are not in Konoha, which could lead to different story arcs and battles.
One possible reason could be for Naruto's safety. Maybe she has to go on a dangerous mission and believes Konoha is the safest place for him. Another reason might be that she is forced by some powerful enemies who threaten Naruto's life if she doesn't leave him in Konoha.
One possible reason could be for his safety. Konoha is a well - protected village with many skilled ninja. She might believe that leaving him there would ensure he has the best chance at survival and growth as a ninja. Also, she may have some mission or obligation that forces her to leave him behind, perhaps something related to the greater good of the village or the ninja world in general.
It also affects the perception of other characters. For instance, the villagers might see Naruto in a different light if Kushina is openly blaming him. They could either side with Kushina, thinking she's right in her concerns, or they could support Naruto, seeing him as a victim of unfair blame. This can lead to new alliances or rivalries within the village.
Well, if Naruto and Kushina left Konoha in fanfiction, it would change a great deal. Naruto would not have the same relationships with his friends like Sasuke and Sakura. He might develop different fighting styles as he wouldn't be trained by the same people in Konoha. Kushina, being a strong kunoichi, could train Naruto in her own unique ways. And their departure could also cause a stir in Konoha, with some people trying to find them and others realizing the mistakes they made in how they treated Naruto and his family in the past.
It could change the family dynamics completely. For example, Naruto's story as we know it might be very different. Instead of growing up an orphan, he could have a very different upbringing with both his parents around. Also, it could affect the power balance in the village as Naruti and Kushina's combined power and influence would be different with a family to consider.
This kind of fanfiction could add a lot of depth to the Naruto universe. It could explore the darker side of Konoha that we may not have seen much in the original series. It could also show how far characters can be pushed until their loyalty breaks. And it might even lead to a redemption arc for Konoha if the story is written in such a way, where they have to change their ways to win back Naruto and Hinata's love for the village.
It could change the power dynamics in the Hidden Leaf. With Kushina back, her knowledge of the Nine - Tails and her strong Uzumaki abilities could shift the balance. For example, if she rescues Naruto from a situation where the village was about to lose him, it would boost the morale of the villagers and ninjas. They would see that there is still hope with someone as powerful as Kushina around. It might also make other villages more cautious about attacking the Hidden Leaf, knowing that Kushina has returned.
One big impact would be on Naruto himself. Having his mother back would give him the family love he always longed for. He would have someone to share his problems and joys with on a more personal level.
One possible reason could be a mission. In many Naruto - related stories, missions often take characters away from their families. Naruto might have received a highly important and dangerous mission that requires him to be away from Kushina for a long time.
In Naruto fanfiction, a Kushina mind - wipe in Konoha could lead to some really interesting plot twists. Maybe it could be part of a scheme by an enemy to disrupt Naruto's life further. Since Kushina was Naruto's mother, her having a mind - wipe would change the dynamics of how Naruto discovers his family history and heritage.
